IMPROVEMENT IN METAL-BACKED COMES.

The Schedule referred to in these Letters Patent and making part of the same We, EDWARD EDMONDS WARNER, 'JAcon WIL- LIAM WALTON, and RoBEnT'VINn, all of Philadel phia, county of Philadelphia, State of Pennsylvania, have invented an Improvement in Metal-backed Confbs, of which the following is a specification.

Nature and Olycct of the Invent-ion.

Our invention consists of a method of fastening metal backs to combs, by means of solder or cement, adapted to the interior of the projecting ends of the metaL-back, and to recesses or projections of the ends of the comb, as fully described hereafter, the object of our invention being 'to produce a strong metal-backed comb of neat appearance, and with none of the objections common to metal-hacked combs fastcned'by the usual method,

Description of the Accompanying Drawing. Figure 1 is a side vicwof our improved metal- .backcd comb;

General Description.

Metal backs are usually attached to combs by forming on each-side of the latter a longitudinal groove, into which the metal composing the back is pinched.

This plan is objectionable for two reasons; first, on account of the labor of forming the grooves on both sides of and throughout the entire length of the comb and, secondly, because these grooves so weaken the comb that it frequently becomes broken ofi beneath the metal back, notwithstanding the additional strength imparted by the latter.

Metal backs have also been riveted to combs, but backsthus attached are apt to become loose, rendering it diflicnlt to keep the 'comb clean.

The object of our invention has been to overcome both of these objections, and to produce a metal-hacked comb of neat appearance, and having a fastening of suificient strength to prevent breaking of the comb or loosening of the back.

On refcrenceto the drawing- A represents the comb, and

B, the sheet-metal back, which is bent over the comb as usual, so as to form the rounded upper edge a.

The lower edges of the metal back are pressed against the flat sides of the comb, as shown in fig. 3, and its opposite ends, which project a short distance beyond the ends of the comb, are bent inward at the lower corners c c, so as to partially embrace the comb, and thus prevent any longitudinal displacement of the back. A notch or recess, 71, is cut in each end of the comb, at a point close to its rear edge, and beneathv the metal back 13, and this notch, as well as the space 2: within the projecting portion of the back, beyond the end of the comb, is filled with a mass of solder or cement, i, which completes the fastening, and efi'ectually prcvents the back from becoming detached.

It will thus be seen that, by simply uotching or recessing the ends of the comb, and filling the same, as well as a portion of the metal back, with solder or cc ment, at more efi'cctual fastening can be obtained than by the objectionable rivets or longitudinal grooves cut in the comb.

The same result might also be obtained by having a projection at each end of the comb, or by inserting in the comb a pin, z, around which to cast the solder or cement, as shown in fig. 1. In this latter case, especially if solder were used, it would be preferable to employ a metal pin, as the comb and back would then be actually soldcrcd together.

Claim A metal-backed comb, in which the metal back is secured to the comb by soft solder, or other soft metal or cement, within a space, a, of the back, and inclosing a projecting portion of, or extending into a recess in the comb, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
